The Carriage by Air Act, 1972
General and Final Provisions
32. Any clause contained in the contract and all special agreements entered into before the damage occurred by which the parties purport to infringe the rules laid down by this Schedule, whether by deciding the law to be applied, or by altering the rules as to jurisdiction, shall be null and void. Nevertheless for the carriage of goods arbitration clauses are allowed, subject to these rules, if the arbitration is to take place in the territory of one of the High Contracting Parties within one of the jurisdiction referred to in rule 28.
33. Nothing contained in this Schedule shall prevent the carrier either from refusing to enter into any contract of carriage, or from making regulations which do not conflict with the provisions of this Schedule.
34. This Schedule does not apply to international carriage by air performed by way of experimental trial by air navigation undertakings with the view to the establishment of a regular line of air navigation, nor does it apply to carriage performed in extraordinary circumstances outside the normal scope of an aircarrier's business.
35. The expression "days" when used in these rules means current days, not working days.
36. When a High Contracting Party has declared at the time of ratification of or of accession to the Convention that sub-rule (1) of rule 2 of these rules shall not apply to international carriage by air performed directly by the State, its colonies, protectorates or mandated territories or by any other territory under its sovereignty suzerainty or authority, these rules shall not apply to international carriage by air so performed.
